Yes, before you install the new xen, do a make uninstall and rebuild the new source. Beware that it removes all xen related files from your boot directory. So make a backup of all the xen-syms, xen-kernels from the directory you boot from.

I made a clean install of Xen 3.0.3, and it doesn''t work if I want to have more than 4 bridge devices: Link veth4 is missing. This may be because you have reached the limit of the number of interfaces that the loopback driver supports. (...) # dmesg|grep loop loop: loaded (max 8 devices) When I uninstall Xen 3.0.3, and install Xen 3.0.2, I don''t have this problem anymore. Uninstall Xen 3.0.2 and install 3.0.3 - problem comes back. So I guess something''s borked in Xen 3.0.3. # brctl show bridge name bridge id STP enabled interfaces xenbr0 8000.feffffffffff no peth0 vif0.0 xenbr113 8000.000000000000 no xenbr128 8000.feffffffffff no peth0.128 vif0.3 xenbr511 8000.feffffffffff no peth0.511 vif0.2 -- Tomasz Chmielewski http://wpkg.org _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
